3c905B, the RX and TX reset commands also reset the cyclone chip's internal
PHY, which causes it to restart its autonegotiation session. This takes a
second or two to complete, which makes the interface seem to stop responding
for a few seconds every time you do something that reinitializes it.
Issuing the RX and TX resets on the older 3c905 boomerang adapters doesn't
cause any delay because the boomerang chip requires an external PHY.
This should fix the problem where people doing network installs via 3c905B
cards experience a delay after the interface is first initialized, among
other things.

METEOR_INPUT_DEV2 now selects a composite camera on the SVIDEO port.
For true SVIDEO, use METEOR_INPUT_DEV_SVIDEO.
If you get a monochrome image from the SVIDEO port, you have
seleted the wrong input type.

reports the TI vendor/device ID, but it appears that some Racore adapters
work this way, and failing to account for it when we have the ID listed

The previous code just ignored the invalid map register, but this gave
surprising results because of the way pci_map_port() associated the map
register offset supplied with a map entry in the map array.
to look up cookies properly, at least for standard controllers.
Cookies are used so that we don't have to pass around lots of args.
All of the dmainit functions use the unit number so it is essential
that we pass them a cookie with the correct unit number.
This may break working configurations if there are bugs in the
dmainit functions like the ones I just fixed for VIA chipsets.
Broken in: rev 1.4 of ide_pci.c and rev.1.139 of wd.c.
Prefetch/postwrite was enabled for the wrong controller. (VIA
is bitwise big endian and we confused ourself by shifting left
instead of right.)

Instead of initializing UDMA mode, we turned it off and made sure that
it stays off by turning on the "UDMA enable by SET FEATURES" disable.
The damage was limited by bugs in cookie lookup, and suitable
initialization by some BIOSes. The cookie list has slaves before
masters, and the unit number is ignored when cookies are looked up,
so cookie lookup always finds cookies for slaves and the bug only
clobbers slaves, so the bug was harmless for common configurations
with no slaves or only non-UDMA slaves. UDMA initialization for
masters actually worked if the BIOS turns on the UDMA mode bit and
turns off the "UDMA enable by SET FEATURES" disable.
- In wb_rxeof(), if the received packet is less than MINCLSIZE bytes,
copy it to an mbuf chain so as to be more frugal in our use of mbuf
clusters.
- The Winbond chip, like the ASIX, wants the 'TX interrupt request'
bit set in the _first_ fragment of a transmitted frame, not the
last. (At least the Winbond manual states this unambiguously; too
bad I wasn't paying attention when I read it the first time.)
- Turn off the transmit threshold mechanism (initialize the threshold
to 0). This effectively puts the chip in 'store and forward' mode
which seems to cut down on transmit errors a little. It may also
reduce transmit performace a bit, but I'm willing to do that if it
means better reliability.
- Normally, the driver allocates an mbuf cluster for each receive
descriptor. This is because we have to be prepared to accomodate up to
1500 bytes (a cluster buffer can hold up to 2K). However, using up a
whole cluster buffer for a tiny packet is a bit of a waste. Also,
it seems to me that sometimes mbufs will linger in the kernel for
a while after being passed out of the driver, which means we might
drain the mbuf cluster pool. The cluster pool is smaller than the
mbuf pool in general, so we do the following: if the packet is less
that MINCLSIZE bytes, then we copy it into a small mbuf chain and
leave the mbuf cluster in place for another go-round. This saves
mbuf clusters in some cases while still allowing them to be used
for heavy traffic exchanges with lots of full-sized frames.
- The transmit descriptor has a bit in the control word which allows
the driver to request that a 'TX OK' interrupt be generated when
a frame has been completed. Sometimes, a frame can be fragmented
across several descriptors. The manual for the real DEC 21140A says
that if this happens, the 'TX interrupt request' bit is only valid
in the descriptor of the last fragment. With the ASIX chip, it seems
the 'TX interrupt request' bit is only valid in the descriptor of
the _first_ fragment. Actually, the manual contains conflicting
information, but I think it's supposed to be the first fragment.
To play it safe, set the bit in both the first and last fragment to
be sure that we get a TX OK interrupt. Without this fix, the driver
can sometimes be late in releasing mbufs from the transmit queue
after transmission.
if option CY_PCI_FASTINTR is configured and mapping the irq to a
fastintr is possible. Unfortunately, this has to be optional because
pci_map_int_right() doesn't handle the INTR_EXCL flag right --
INTR_EXCL is honoured even if the interrupt needs to be non-exclusive
for other devices to work.
using the new pci_map_int_right() variant of pci_map_int(). Fast
interrupts work for PCI devices if and only if they are exclusive.
(The PCI interrupt mux doesn't support fast interrupts and can't
support a mixture of fast and slow interrupts even in principle.)
Don't assume that intrmask_t == unsigned in pci_map_int().
